I agree with you. I have a Safari subscription and I have mostly stopped buying computer science text books (I buy only 7 or 8 a year now). Now instead of looking on stack overflow or doing a web search, I login to Safari, find a recent book, and read the parts that are useful/interesting.
Same. When I got an email yesterday saying that my ACM membership now gives me complete access to the entire Safari platform and all its content, it was like the last several Christmases all wrapped up in one. Just extraordinary how much useful content just became available to me, and all searchable too. Amazing.
